"SENTAR has been providing top notch mission critical software development for the GMDS Payload Launch Vehicle Ground Support Software for over five years. This has made possible the successful launch and boost phase flight control for the flight tests necessary to support this key national defense program. SENTAR people always get the tough jobs done right and on schedule."

Sentar provides the LMMS customer with experienced software developers for the design, development and maintenance of the PLV GSS. The GSS is responsible for prelaunch testing and launching the PLV and guiding it to a point in space. When the PLV reaches the specified location in space, a Exoatmospheric Kill Vehicle (EKV) is deployed with the intent of intercepting a ballistic target. The GSS includes multiple processes executing on multiple Sun Sparcstation 20 computers to accomplish this incredibly complicated task. Sentar supported the development of GSS from the beginning requirements phase to the current maintenance phase. Support has included requirements analysis, object oriented design using the Shlaer-Mellor methodology, Ada and C/C++ development, unit testing, and technical leadership. Sentar process experts defined the software processes used for GSS development. During critical test missions, Sentar employees are called upon to travel to the Kwajalein Atoll of the Marshall Islands in the Pacific Ocean for technical support. As a result of a 100 percent launch success rate, Sentar has won repeat business from LMMS for the last five years.

ISTC Integration/ISTC Monitoring and Support Software

Sentar provides the LMMS customer with an experienced team of software developers and analysts for the development and maintenance of the ISTC PLV/GSE product. ISTC is a generic test bed maintained at the Advanced Research Center (ARC) and GBR Development Integration Lab (GDIL) in Huntsville, AL. In addition, the PLV/GSE software is also provided to the System Integration Lab (SIL) test bed. PLV/GSE is used in risk reduction activities for the LMMS Ground Support Software (GSS) such as pre-mission tests and post-test analysis. The core of the PLV/GSE product is GSS launch code. The development team integrates the representative GSS code with a LMMS developed PLV booster model and then adapts it to run in the ISTC test environment. PLV/GSE allows investigators to determine how the GSS code will behave on flight day regardless of if that date is in the past or in the future. Sentar support for PLV/GSS has included requirements analysis, object oriented design using the Shlaer-Mellor methodology, Ada, and C/C++ development and technical leadership.

Sentar provided Software Process Engineers (SPEs) in support of Lockheed Martin's System Software Engineering (SSE) department for the Theater High Altitude Area Defense (THAAD) Engineering and Manufacturing Development (EMD) phase. Sentar's support of this project included the development of standard software engineering and management processes and procedures, developing the Software Process Assets Repository (SPAR),   supporting training activities, and ensuring team members were implementing the defined processes. This support activity provided a plan for Lockheed Martin Missiles & Space to obtain SEI CMM® Level 3 - The Defined Level. Sentar's SPEs  also defined and developed the certification plan to move to Level 4 - The Managed Level.

"When Alphatech wanted a partner to develop software for missile defense BMC3 we turned to SENTAR. SENTAR has a reputation for high quality work and dependable performance. SENTAR has stepped up to the job, taking a solid technical lead role on the software and has delivered quality products, on schedule and within budgets. We are very pleased with our partnership and look forward to expanding our work together."

BMC3 System Architecture, System Engineering, Software Development

Sentar supported USASSDC as a key player in the evolving NMD BMC3 capability.

• Performed BMC3 system design and analysis
• Tested and evaluated communication network
• Developed High-Fidelity model
• Developed performance evaluation methods
• Performed independent verification and validation
• Supported system architecture analysis and development

• Developed BMC3 architecture
• Evaluated BMC3 system designs
• Developed and applied software reuse evaluation methods
• Supported simulations
• Developed and analyzed concepts for future technology insertions

• Created an abstract/generic map interface, which allowed ITADS to drive a map without it actually knowing the “exact” map instance/application.
• Created an IPC-application based on MS COM out-of-proc server which allowed the ITADS map functionality to be implemented by another process (hosting an Autometer/Edge based map).
• Created an Autometer COM-Layer in-proc server, which interfaced/translated the abstract/generic map interface methods with/to Autometer/Edge API and concepts.
• Created an Autometer/Edge base map application for managing/hosting the COM layers.
